Titles are "Clipping Masks & Color Mapping", "Depth of Field Processing" and "Multi Strength Decon Layer Blend". There's also a PowerPoint presentation entitled "Six Filter Narrowband Processing" which has been converted into a set of PDF files.

This page links to another set of video tutorials but also be sure to check out the Image Gallery and judge the author by the quality of his work. I only came across this site by chance today as, though it is by Don Goldman of Astrodon and hosted on the Astrodon server, I've never seen a link to it from the main Astrodon pages.

This is an information rich site which can be hard to navigate if you are looking for something specific!

Version 1 of Tone Mapping is described on the page linked to above and is downloadable as a PDF. This includes a description of using PhotoShop's "Dust & Scratches" filter to remove stars. Version 2 of Tone Mapping is described here by means of a few JPEGs but I haven't been able to find an equivalent PDF yet.

I've not had a chance to review most of the tutorials above yet, let alone put them into practice, but I thought I'd share and see if we can make this thread into a useful resource. If that happens I might even suggest to Gordon that it becomes a "Sticky".

.There are a number of bite sized PhotoShop tutorial if you follow the links at the bottom right of the Atlas Astronomy site. Some aren't as well structured as I would like but there is further confirmation that "Layers" can be an astrophotographer's best friend.
